Method for producing iron powder

China's manufacturing industry must change the mode of growth, green manufacturing will become the direction of sustainable development of China's manufacturing industry. By the change of the growth mode of the manufacturing industry, to further promote the development of China's powder metallurgy industry, commonly known as iron powder, its accurate name should be iron and steel powder.

Powder metallurgy material is closely related to our life, not only in the automotive, aerospace, military and other industries is an essential material, but also in the refrigerator, washing machine, air conditioning and other household products are also a large number of applications. China is now the production of iron and steel powder mainly has four kinds of methods: atomization, reduction, electrolysis and carbonyl. Carbonyl method can obtain nanometer powder, purity is high, the cost is very high, mainly for the military field; electrolytic method almost can produce all metal powder, fewer impurities, high purity, used for chemical industry; reduction method and spray method is the more economic and yield large iron and steel powder preparation method that is widely used in mechanical manufacturing industry, large quantities of parts and components production.
